What are Index laws for kids?
What are index laws?
- When multiplying powers of the same base number, you add the powers.
- When dividing powers of the same base number, you subtract the powers.
- When raising one power to another, you multiply them.
- Anything to the power 1 is just itself.
- Anything to the power 0 is just 1.
- 1 to any power is just 1.
What are the 5 rules of indices?
Laws of indices
- (read as ‘ squared’) means a × a . has been multiplied by itself twice. The index, or power, here is 2.
- (read as ‘ cubed’) means a × a × a . has been multiplied by itself three times.
- (read as ‘ to the power of 4’) means a × a × a × a . has been multiplied by itself four times, and so on.
What is the 4th index law?
In general: This formula tells us that when a power of a number is raised to another power, multiply the indices. This is the fourth index law and is known as the Index Law for Powers.
What is the 2nd index law?
In general: This formula tells us that when dividing powers with the same base, the index in the denominator is subtracted from the index in the numerator. This is the second index law and is known as the Index Law for Division.
What is the 2 index law?
What does index mean in math?
An index, or a power, is the small floating number that goes next to a number or letter. The plural of index is indices. Indices show how many times a number or letter has been multiplied by itself. Here is a number written in index form: 2 is the base number and 4 is the index or power.

What is the 6th index law?
In general: This formula tells us that when a quotient is raised to a power, both the numerator and denominator are raised to the power. This is the sixth index law and is known as the Index Law for Powers of Quotients.
